Method for performing data communication in wireless communication system and terminal using same method

Abstract

The present invention provides a data communication performing method performed by a terminal in a wireless communication system, the method comprising: determining a resource configured for data communication having a relatively short latency requirement; and performing, on the resource, the data communication having the relatively short latency requirement, wherein the resource is a semi-statically configured resource.

What is claimed is: 
     
       1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
 determining resources that are semi-statically configured for a first data communication; and 
 performing, on at least one of the resources, the first data communication, 
 wherein the first data communication has a relatively short latency requirement compared to a latency requirement of a second data communication, 
 wherein, in case the first data communication is performed, puncturing a resource for the data communication is performed, and 
 wherein, in case the first data communication is not performed, puncturing a resource for the data communication is not performed. 
 
     
     
       2. The method of  claim 1 ,
 wherein the first data communication having the relatively short latency requirement, compared to the second data communication, is an ultra reliable and low latency communication (URLLC), and 
 wherein the second data communication having a relatively long latency requirement compared to the first data communication is enhanced mobile broadband (EMBB). 
 
     
     
       3. The method of  claim 1 ,
 wherein the resources comprise at least one of first type of resource or second type of resource, 
 wherein the first type of resource is a resource for which puncturing is always applied, and 
 wherein the second type of resource is a resource to which puncturing is applied depending on whether data communication having a relatively short latency requirement is performed. 
 
     
     
       4. The method of  claim 3 , wherein the first data communication is performed using the first type of resource, based on a channel state not being better than a threshold value during a specific duration. 
     
     
       5. The method of  claim 3 , wherein the first data communication is performed using the second type of resource, based on a channel state being better than a threshold value during a specific duration. 
     
     
       6. The method of  claim 3 , wherein the first type of resource is relatively small in size relative to the second type of resource. 
     
     
       7. The method of  claim 3 , wherein the first type of resource has a separate reference signal (RS). 
     
     
       8. The method of  claim 1 , further comprising:
 receiving, from a network, information indicating a communication direction on the resources. 
 
     
     
       9. The method of  claim 1 , further comprising:
 receiving, from a network, a time duration in which the resources are valid. 
 
     
     
       10. The method of  claim 1 , further comprising:
 transmitting, to a network, assistance information related to the resources. 
 
     
     
       11. The method of  claim 10 , wherein the assistance information includes information indicating how long the data communication is performed. 
     
     
       12. The method of  claim 10 , wherein the assistance information includes information about whether at least one parameter for the resources is suitable for the first data communication. 
     
     
       13. The method of  claim 10 , wherein the assistance information includes at least one of release information for the resources or change request information for the resources. 
     
     
       14. A user equipment (UE) in a wireless communication system, the UE comprising:
 a transceiver; and 
 a processor operably coupled to the transceiver and configured to: 
 determine resources that are semi-statically configured for a first data communication; and 
 perform, on at least one of the resources, the first data communication, 
 wherein the first data communication has a relatively short latency requirement compared to a latency requirement of a second data communication, 
 wherein, in case the first data communication is performed, puncturing a resource for the data communication is performed, and 
 wherein, in case the first data communication is not performed, puncturing a resource for the data communication is not performed.
